Interviewed there in December. Like hbk4321 said, it's a 15 minute closed file interview with two faculty members (they have a timer set for 14 minutes). It's supposed to be one of the shortest interviews compared to other schools. They asked what would be considered typical interview questions. Why optometry? Why CCO? I don't remember much from the interview itself, but mine lasted 30 minutes because I ended up vibing with the professors and the interview became very conversational. Depending on what wave you're in, you'll either interview first or receive a tour of the building first. From there, they had students show us around campus, before we had lunch. We ended the day with a tour of the clinic, which is a bit further away. I heard back from CCO the very next morning. To prepare, I recommend that you look over questions that students have submitted about their interview day for CCO on here. I would not be stressed about the interview, since the default interview time is very short. Even 30 minute interviews felt like there wasn't enough time to talk about all of my strengths.
